MACHINE FOR SOFTENING HIDES OR SKINS.

SPECIFICATION forming part of Letters Patent No. 620,545, dated February28, 1899.

Application led September 23, 189?. Serial No. 691,692. (No model.)

T0 all whom, it muy concern.:

Be it known that I, GEORGE V. GLAZIER, a citizen of the United States,residing at Salem, in the county of Essex and State of Massachusetts,have invented new and useful Improvements in Machines for SofteningHides or Skins, of which the following is a specication.

This invention relates to improvements on the patent granted October 30,1888,' No. 392,141, to Nicolas lVeber for a machine for softening. hidesor skins; and it consists in improved and simplified mechanismforopening and closing the hide or skin gripping devices, as willhereinafter be more fully shown and described, reference being had tothe accompanying drawings, wherein- Figure l represents a side elevationof the improved machine, showing the yielding roll and the scraper asbeing closed against opposite sides of the hide or skin during thebackward movement of the gripping device. Fig. 2 represents alongitudinal section of the machine, showing the gripping mechanism eX-panded during its forward movement; and Fig. 3 represents a detailbottom plan view of the forward end of the roller-carrying lever andmeans for adjusting said roller relative to the scraper during theoperation of the machine.

Similar letters refer to similar parts whereever they occur on thedifferent parts of the drawings.

In the drawings, A represents the frame of the machine, in bearings inwhich is j ournaled the rotary driving-shaft B, to. which is attachedthe balance-wheel C, having a crank D, to which is pivotally connectedthe link orconnecting-rod E, the forward end of which is pivotallyconnected at e to a bracket F, having made integral with :it a carrierF', which is adapted to move longitudinally in suitable guides in theframe A, as shown.

Integral with the carrier F' is made an upwardly-projecting bracket F ina manner similar to that shown and described in the VVebe'r patent abovementioned.

G is the scraper-carrying lever, which is pivoted at g to the bracketF", and it is provided at its forward end with a preferably curved bladeor scraper H, adapted to remove the surplus matter from the flesh sideof a hide or skin I, interposed between it and the elastic roller K,which is journaled on the under -side of the forward end of a lever L,pivoted at Z to the bracket F", as shown.

Back of the scraper H is secured to the lever G a blunt blade 71,serving to remove wrinkles from the hide or skin in advance of the pointwhere the scraping-blade acts in a 6o manner similar to that shown anddescribed in the above-mentioned patent.

It will be noticed that a longitudinal forward-and-back vmovement isimparted by the crank D and connecting-rod E to the carrier F', itsbracket E', and the levers G L, pivoted to the latter.

The mechanism for automatically holding the roller K against theScrapers H h and the hide or skin interposed between such roller 7o andscrapers during the backward movement of the levers G L is constructedas follows: m is a rock-shaft journaled in a bracket f, madeintegralwith the slide E and bracket E", and to said rock-shaft issecured a cam M, adapted when rocked during the backward movement of thelevers G L to come in contact with the rear portions of said levers, (oradjustable plates secured thereto,) by

which the forward ends of said levers are 8o closed sufficiently topress the skin or hide 'with a proper friction between the roller K andScrapers H h.

To the rock-shaft m are secured cranks N N, to which are pivotallyconnected links or rods N N', the lower ends of which are pivotallyconnected to the Vlever E, and it will thus be seen that a rockingmotion is imparted to the cam M directly from the connecting-rod Eduring the rotation of the shaft B. 9o for the purpose stated.

During the forward motion of the carrier F' and the levers G L, pivotedtoit, the cam M` ceases to act on said levers, and they are thenautomatically expanded, as shown in Fig. 2, by the inuence of a springor springs O, connected to the rear ends of said levers G L, as shown inFigs. l and 2.

R represents the work-supporting table secured in a suitable manner tothe frame A, Ice and to its outer end is secured a rubber cushion or barS to enable the operator .to better hold the skin during the scrapingaction by bearing the same against said cushion or roll with his body ina manner like that shown and described in the Weber patent aforesaid.

In machines of this kind it is very desirable to enable the operator toadjust the roller K relative to the scraper H during the operation ofthe machine, so as to compensate for variations in the thickness of thehide or skin that is being operated on, and for this purpose I journalthe roller K in a plate or bracket T, which is longitudinally adjustableon the lever L or a plate t, attached thereto, as shown in the drawings.p

In practice I prefer to adjust the position of the roller K by means ofa hand-wheel V, attached to a spindle journaled in the plate T andprovided with a bevel-gear V', meshing in a similar gearV", attached toa screwthreaded spindle V3, journaled in the plate t and working in ascrew-threaded perforation on the bracket or slide T, as shown in detailin Fig. 3. It will thusbe seen that the operator can readily adjust theposition of the roller K relative to the scraper I-I simply by turningthe hand-wheel V during the operation of the machine, as may berequired, according to variations in the thickness of the hide or skinoperated upon.

I prefer to adj ust the roller K by means of the hand-wheel, gears, andscrew, as described; but I wish to state that I do not confine myself tothis exact arrangement, as equivalents may be used without departingfrom the essence of my invention.V

What I wish to secure by Letters Patent and claim is- 1. In a machinefor softening hides or skins in combination, a rotary crank or wheel, areciprocating carrier, a connecting-rod between said parts, a pair ofspring-pressed levers pivoted to said carrier, a rock-shaft intermediatebetween said levers, a cam and crank secured to said rock-shaft, a linkconnecting said crank and connecting-rod and a roller and scrapingdevice attached to the forward ends of said levers, substantially as andfor the purpose set forth.

2. In a machine forsoftening skins or hides, in combination, areciprocating carrier, a pair of scraper-levers pivotally connected'tosaid carrier, a spring for expanding said levers and a cam forv closingsaid levers said cam being actuatedvby a link connected to theconnecting-rod that imparts a reciprocating motion to the carrier,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witmesses.
